Abstract: A power over Ethernet (PoE) power supplying method where power sourcing equipment (PSE) and a powered device exchange link layer discovery protocol data units (LLDPDUs). Each of the LLDPDUs includes two power values. Each of the power values indicates requested or allocated power for one of two sets of cable pairs of the Ethernet twisted pair connecting the PSE and the powered device. Accordingly, the supplied powers to the powered device at sets of cable pairs are independent from each other.

Abstract: An antenna array and a wireless communications device are disclosed. The antenna array includes at least two directional antennas in different directions. Each directional antenna includes an antenna element, a reflector, a feed line coupled to the antenna element, and a switch for controlling the feed line. The antenna element is a microstrip dipole antenna element. The reflector is a parasitic microstrip antenna element. A length of the reflector is greater than a length the antenna element. Two ends of the reflector are bent toward the antenna element. A distance between midpoints of reflectors of any two directional antennas is less than a distance between midpoints of antenna elements thereof. Because the reflectors of the antenna array are located on an inner side of a pattern enclosed by the antenna elements of directional antennas, a size of the antenna array is small.

Abstract: A network device probes whether a first port of the network device is coupled to power sourcing equipment, and when probing that the first port is coupled to power sourcing equipment, maintain or change the first port to a powered state, and lock the first port as a power drawing port, or when probing that the first port is decoupled to power sourcing equipment, and the network device has a power supply for supplying power, change the first port to a powering state. In this way, the first port may adaptively serve as a power drawing port or a power sourcing port according to a coupled device such that manually distinguished a port during device interconnection is not necessary and a coupling error rate is reduced.

Abstract: A power over Ethernet method includes: performing, by power sourcing equipment, a plurality of detections by using an Ethernet port, connected to an intermediate device, of the power sourcing equipment, where a quantity of detections performed by the power sourcing equipment is equal to a quantity of power supply ports of the intermediate device; and if at least one detection result of the plurality of detections is effective, sending, by the power sourcing equipment, a power supply indication to the intermediate device, and supplying power to the connection port. In this way, the power sourcing equipment can supply power across the intermediate device to a powered device connected to the intermediate device, and a power loss caused by voltage conversion is avoided.

Abstract: A power supply management method performed by power sourcing equipment, includes receiving a power-on request from a level-1 powered device, where the power-on request includes a port identifier of a level-2 power supply port that is detected to be valid in the level-1 powered device, determining, based on the power-on request and an outputtable power of the power sourcing equipment, a level-2 power supply port that is allowed to be powered on in the level-1 powered device, and sending a power-on instruction to the level-1 powered device, where the power-on instruction includes a port identifier of the level-2 power supply port that is allowed to be powered on in the level-1 powered device. The power sourcing equipment uses the level-1 powered device and a level-2 powered device connected to the level-1 powered device as a whole, and centrally performs power supply control and power management.
